Triviality in a Non-Perturbative Second-Order Mean-Field Theory for
Majdouline Borji
We introduce a second-order mean-field description of the four-dimensional Euclidean model within the Wilson--Polchinski renormalization-group framework. The construction is…

Perturbative renormalization of the lattice regularized with flow equations
Majdouline Borji, Christoph Kopper
The flow equations of the renormalization group allow to analyse the perturbative -point functions of renormalizable quantum filed theories. Rigorous bounds implying renormaliza…
